T 0 all whom it may concern:

Be it known that we. Faint; (l. and ANTONIN PLAGEK, the former a citizen of the United States and the latter a citizen of Czechoslovakia, both residing Cleveland, in the county of Cuyahoga and Etate of Ohio,,have inventedycertain new and us ful Improvements in Tool-Quenchin Ta and the like of which the follow as is a specification This invention relates to tool quenchin tanks and the like, and has for its main 00-- ject to provide a tank for quenching tools after being heated for tempering same, which is provided with means for conve" in the tools therefrom. Said means cor. of a rotatably mounted drum having wardly extending strips forming pockets tor carrying and delivering the tools into a chute. i

In order that the invention may be clearly understood, the same will be hereiiatter fully described in connection with the ac companying drawings, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings similar characters of ref: erence are used to indicate corresponding parts.

Figure 1 is a section elevation of a quenching tank constructed in accordance with our invention,

Fig. 2 is a cross section of the drum taken on line 2-2 of Fig. 1, and

Fig. 3 is a similar view illustrating a modification.

Referring to the drawings, 1 represents a tank constructed of sheet metal or other suit-'- able material for containing oil or other quenching fluid into which tools to be tempered are dropped. In order to automatically remove the tools after being dropped into the quenching tluid a longitudinally arrtnged drum 2 is rotatably mounted upon rollers 3, 4 and 5 carried by the sides of the tank. Said drum is provided with rings 6 and 7 for supporting it upon said rollers, and the bottom of the drum is located below the topot the tank and is adapted to rotate under the quenching fluid. in the tank. Any suitable means may be employed for rotating the drum. as for instance a driving pinion 8 meshing with a ring rack or spaced rollers at 9, One end of the drain 2 is provided with a circular opening 10 for receivinga chute 11 for guiding the tools into the bottom ot the Ilrum and the oth r nd with similaropen- 12 for perm a delivery chute 13, wh ch is arranged i hin said drum, to GK- tend there'li: The upp end the deli\ v1y chute 13 lower end at Fixed to the inner Sit of the drnnifZ are longitudinally extending s rips 16 which have their inner or free ages bent toward the inner sides of ti drum and upwardly with relation to its iection oil. rotation For forming pockets carrying the tools "to the delivery 18. The tools fall from the receiving "1e 11- into the bottom oi thedrum 2 bestrips 15, and a counter-clockwise, said strips 16 or pockets 1'? formed thereby carry the tools upwa ally and when the pockets over L K he delivery chute, the tools slide therefrom l in o said chute.

in some cases when it is desirable to employ a drum of large diameter as 18 and rotate said drum slowly, and use a wide delivery chute as is indicated at 19, longitudinal strips 20 instead of 16 are tired to the inner sides of the drum. 20 are similar to the strips 16 except that their inner or free edges are bent down wardly at 21, which form pockets at 22 and otiers at The tools as before fall into the bottom of the drum between the strips 520 and are carried upwardly by the pockets 9 2, and when they are at the top of the drum. and over said delivery chute, some of the tools slide therefrom into said chute and others all into the pockets 2o of the next forward strip and may slide therefrom into said chute but from the opposite direction.

In operation the tools pass down the receiving chute 11 into the quenching fluid in the bottom 01"? the drum 2. and the rotation of the drum causes its side strip 16 to lift the tools into the delivery chute 13.

Having fully described our invention, what we claim is:

1. In a tool cnienchingtank and the like, the combination of a tank for holding a fluid, a drum the drum being rotatably mounted, the lowerpart of the drum being adapted to pass through the fluid, a delivery chute extending from the upper is suoported at 14 and its the drum re- 7 The strips v of the drum, the delivery chute extending the entire length of the drum, and. the drum having means for carrying tools to the delivery chute, substantially as described,

2. In a tool quenching tank and the like, the combination of tank for holding a fluid, a drum, the drum being rotatably mounted, the lower part of the drum being adapted to pass through the fluid, a delivery chute extending from the upper part of the drum, the delivery chute extending the en tire length of the drum, and strips fixed to the inner sides of the drum for carrying tools into the delivery chute, substantially as described.

3. In a tool quenching tank and the like, the combination of a tank for holding a fluid, a drum, the drum being rotatably mounted, the lower part of the drum being adapted to pass through the fluid, a delivery chute extending from the upper part of the drum, the delivery chute extending the entire length of the drum, strips fixed to the inner sides of the drum, and the strips being bent toward the inner sides of the drum and upwardly with relation to its direction of rotation for forming pockets for carrying tools into the delivery chute, substantially as described.

4. In a tool quenching tank and the like, the combination of a tank for holding a Fluid, a drum, the drum being rotatably mounted, the lower part of the drum being adapted to pass through the fluid, a delivery chute extending from the upper part of the drum, strips fixed to the inner sides of the drum, and the strips being bent toward the inner sides of the drum and upwardly with relation to its direction of rotation and then downwardly for forming upper and lower pockets for carrying tools upwardly and directing them into said delivery chute, substantially as described.

In a tool quenching tank and the like, the combination of a tank for holding a fluid, a drum, the drum being rotatably mounted, the lowerpart of the drum being adapted to pass through the fluid, the drum having openings in its ends, a receivin chute entering the drum through one en opening, a delivery chute arranged above the receiving chute and extending the entire length of the drum and. through the other end opening of the drum, and the drum having means for carrying tools to the delivery chute, substantially as described.

In testimony whereof we afiix our signatures.
